My research in behavioral ecology uses integrative approaches to study coevolution between predators and prey. These dynamic interactions show remarkable sophistication, from ground squirrels using rattling they provoke in rattlesnakes to assess the body size and temperature of their reptilian enemies, to grasshopper mice capable of feeding on highly neurotoxic scorpions because of subtle modifications in the mouse's peripheral nerves. My conservation biology research examines habitat selection and habitat requirements in vertebrates. My two interests are not as disparate as they first appear; basically, I am fascinated by the relationships among species within a community.
